Jones' 19 completions and 288 yards were both career highs, and he threw for two touchdowns in the Buckeyes' 38-12 win.

On the other hand, by Meyer's count, Jones underthrew six deep passes, and he could have tossed for more than 500 yards if he hit each of them.

"Fundamentally he wasn't sound," Meyer said. "The way he transferred back to front, dragging his back leg, and that's (quarterbacks coach) Tim Beck, and they'll work at it. And then J.T. underthrew one too. J.T., if you remember early last year, struggled with that, and then he started throwing beautiful deep balls.

"So that's just something you've got to work on. But you can see certainly in that arm strength, it's just the fundamental flaw of not being able to weight transfer and driving the ball. Because he had one of his better days throwing. The underneath, the two-minute drill, some of those were just rocket shots he was throwing and very aggressive, and fundamentally right on it, some deep balls.

"It was alarming. I want to say at least six (were off target). I should have that number for you, but at least six balls. That was a 518-yard day. Those are those days that if you hit those, that's a big day."

For his part, Jones understood that he needed to do better on those shots down the field.

"It's on me," Jones said. "You just have to go back and watch. Every underthrown ball, the receiver had a guy beat by a significant amount of yards. They're easy layups. Coach Meyer pulled me to the side like, 'That's your strength, that's what helped us get to this point.' I have to complete them. I have to get back in the film room and the practice field and get it fixed."
